Which versions of the Android NDK support 64-bit architectures?

Issue

According to the Android Developer website, Starting August 1, 2019, your apps published on Google Play will need to support 64-bit architectures.

Is there any clear documentation that specifies which Android NDK versions support 64-bit architectures? Or a better question is, what tools can I use to find this out for myself (someone will say Google :D)?

Solution

From the NDK Revision History:

Android NDK, Revision 10 (July 2014)

Important changes:
* Added 3 new ABIs, all 64-bit: arm64-v8a, x86_64, mips64.
